Actions
All four quadriceps are powerful extensors of the knee joint. They are crucial in walking, running, jumping and squatting. Because rectus femoris attaches to the ilium, it is also a flexor of the hip. This action is also crucial to walking or running as it swings the leg forward into the ensuing step. The quadriceps, specifically the vastus medialis, plays the important role of stabilizing the patella and the knee joint during gait.

Famous quotes containing the word actions:
“The actions of each dancer were scrutinized with great care and any little mistake noted and remembered. The strain upon a dancer was consequently so great that when a fine dancer died soon after a feast it was said, “The peoples’ looks have killed him.””
—Merle Colby, U.S. public relief program (1935-1943)
“... nothing is more human than substituting the quantity of words and actions for their character. But using imprecise words is very similar to using lots of words, for the more imprecise a word is, the greater the area it covers.”
—Robert Musil (1880–1942)
“Only the actions of the just
Smell sweet and blossom in their dust.”
—James Shirley (1596–1666)
